Internet2 may change the way scientists conduct research

06.04.2004

When Dr. Robert Ballard went on a scientific expedition to Black Sea this past summer, he was able to take with him virtually any scientist or student who wanted to go. With the capability of Internet2 and a high bandwidth satellite link, scientists, for the first time, were able to work on the ocean floor from the comfort of their university laboratories.

In the April 6 issue of EOS, the weekly newspaper of the American Geophysical Union, Dr. Ballard, a University of Rhode Island geological oceanographer, describes how Internet2 could change the way scientists conduct deep-sea research.

Internet2 is a consortium of 205 universities working with industry and the government to develop and deploy an advanced Internet network that operates at 10 gigabits per second. "Instead of being restricted to one or two scientists working for a few hours within the small confines of a human-operated vehicle," said Ballard, "scientists using remotely-operated vehicles (ROVs) connected to Internet2 could spend an unlimited about of time on the bottom and share, in real-time, their observations with colleagues around the world."

The technology was put to the test this past summer when Ballard and a team of scientists traveled to the Black Sea for a research expedition sponsored in part by the National Science Foundation, the Office of Naval Research and the National Oceanic and Atmospheric Administrations Office of Ocean Exploration, and the National Geographic Society.

Ballard explains in the article that two remotely operated vehicles working at or near the bottom of the Black Sea transmitted eight underwater video images and five acoustic signals via fiber optic cable up to the ships command/control center. Six video signals, including two high-definition images and three two-way audio channels, were transmitted off the ship via satellite, were received by an antenna in the US, and placed on Internet2.

The primary Internet2 site for the expedition was the newly created Inner Space Center at the URI Graduate School of Oceanography (GSO). Through the use of a series of plasma screens, the Inner Space Center replicates the science workstation aboard the ship. From the Inner Space Center, researchers can talk with the shipboard scientists and technicians and request images at various resolutions for examination.

"The Inner Space Center at GSO is being built to make it possible for GSO scientists and students to participate in various sea-going expeditions sponsored by the Office of Naval Research and NOAAs Ocean Exploration program from their laboratories at the URI Bay Campus in Narragansett," said Ballard.

During the expedition Internet2 was also used at the Institute for Exploration and Mystic Aquarium to produce live programming for the general public, who were able to ask questions of the team at sea.

"The cost of physically transporting human beings in small numbers to remote regions of the world and then taking them to the bottom of the ocean in even smaller numbers for short periods of time to explore short stretches of the seafloor is clearly not an efficient way to explore the vast regions of our planet," said Ballard.

The URI Graduate School of Oceanography is one of the countrys largest marine science education programs, and one of the worlds foremost marine research institutions. Founded in 1961 in Narragansett, RI, GSO serves a community of scientists who are researching the causes of and solutions to such problems as acid rain, harmful algal blooms, global warming, air and water pollution, oil spills, overfishing, and coastal erosion. GSO is home to the Coastal Institute, the Coastal Resources Center, Rhode Island Sea Grant, the Institute for Archaeological Oceanography, and the National Sea Grant Library.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
